Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a pipe belt conveyor. Background Art

[0002] The pipe belt conveyor is used to wrap the material in a tubular tape (tube tape) for transportation. Therefore, there is no flying and splashing of material on the load-bearing side during transportation. The pipe belt conveyor's pipe belt moves back and forth between the loading point and the unloading point of the material. The tape on the return side is reversed into a tube shape, and the side of the tape carrying the material is still wrapped inside. This avoids the scattering of residual material on the adhesive tape along the return conveying line, and also prevents the environment (dust, rain, etc.) from polluting the conveyed materials.

[0003] However, in actual operation, it was found that due to the long running belt, when there is excessive material flow, backpacking or damage and deformation of the roller, it is easy to cause the pipe of the pipe conveyor to twist, affecting production. When the pipe is twisted beyond a certain angle, the belt cannot be unfolded in the unfolding section, resulting in serious accidents such as belt overlap, which requires a lot of manpower and material resources to deal with.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment", "some embodiments", "exemplarily" and "one embodiment" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or embodiment are included in at least one embodiment or embodiment of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or embodiments in a suitable manner.

[0030] The terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0031] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a pipe tape machine, including a pipe tape 100, two travel switches 1, a plurality of pipe segment roller rack groups 2 and a plurality of transition segment roller rack groups 4, the plurality of pipe segment roller rack groups 2 are arranged at the upper pipe segment 110 and the lower pipe segment 120 of the pipe tape 100, the plurality of transition segment roller rack groups 4 are arranged at the tail transition segment 130 and the head transition segment 140 of the pipe tape 100, the two travel switches 1 are arranged between the upper pipe segment 110 and the head transition segment 140, the two travel switches 1 are symmetrically arranged on both sides below the upper pipe segment 110, and when the upper pipe segment 110 is twisted, the package mouth of the upper pipe segment 110 is used to contact the contact of the travel switch 1.

[0032] Specifically, the tube tape 100 includes an upper tube section 110, a tail transition section 130, a lower tube section 120 and a head transition section 140 connected end to end in sequence. The tail transition section 130 and the head transition section 140 are unfolded sections, which are unfolded into a plane, a groove, or a deep groove. The upper tube section 110 and the lower tube section 120 are circular tubes. The upper tube section 110 is used to transport materials, and the lower tube section 120 is a return section. The lower tube section 120 is circular tube-shaped and one side of its material bearing surface is still wrapped inside, which can prevent residual materials on the tape bearing surface from scattering along the return transportation line. Figure 2 In the figure, the direction of the arrow refers to the traveling direction of the tube tape 100, and the tail transition section 130 is arranged at the tail of the tube conveyor. At the tail of the tube conveyor, the lower tube section 120 gradually unfolds and transitions from a circular tube shape to a deep groove shape (∩ shape), a groove shape (∧ shape), and a plane shape (one shape). After being wound by a redirecting roller, it gradually transitions to a plane shape (one shape), a groove shape (∧ shape), and a deep groove shape (∩ shape), until a circular tube-shaped upper tube section 110 is formed; the head transition section 140 is arranged at the head of the tube conveyor. At the head of the tube conveyor, the lower tube section 120 gradually unfolds and transitions from a circular tube shape to a deep groove shape (∩ shape), a groove shape (∧ shape), and a plane shape (one shape). After being wound by a redirecting roller, it gradually transitions to a plane shape (one shape), a groove shape (∧ shape), and a deep groove shape (∩ shape), until a circular tube-shaped upper tube section 110 is formed. Figure 7 This is the standard tube drawing of tube tape 100, such as Figure 8As shown, under normal circumstances, the package opening of the upper tube section 110 of the tube tape 100 is at the top. Therefore, during the transportation process, after the material is wrapped by the bearing surface (the inner circumference of the upper tube section 110), the material will not be scattered, flying or splashing. After passing through the redirecting roller, the original bearing surface is reversed to form the lower tube section 120. At this time, the package opening of the tube tape 100 is at the bottom, and the bearing surface is still wrapped on the inside, which can not only prevent the residual material from being scattered along the return transportation line, but also prevent the environment (dust, rain, etc.) from polluting the transported materials. However, in some cases, the upper tube section 110 may experience a twisting phenomenon during the material transportation process, that is, the upper tube section 110 twists around its axis, such as Fig. 9 The figure is a schematic diagram of the upper tube section 110 after the tube is twisted. If the twist angle of the upper tube section 110 is relatively large, for example, reaching about 180°, the tube tape 100 may be easily folded during subsequent unfolding, resulting in the subsequent inability to unfold and form a tube normally.

[0033] It should be noted that the redirecting roller Figure 2 Not shown in the figure, the redirecting roller is an important component of the pipe tape conveyor, and plays a key guiding and supporting role in the operation of the pipe tape 100. The redirecting roller is usually composed of a roller, a bearing, a bearing seat, a sealing device and other components, which can ensure that the pipe tape 100 can smoothly transition at the turning point between the tail transition section 130 and the head transition section 140 to avoid problems such as deviation or folding.

[0034] In this embodiment, two travel switches 1 are arranged between the upper tube section 110 and the head transition section 140, and the two travel switches 1 are symmetrically arranged on both sides of the lower part of the upper tube section 110. In this way, when the upper tube section 110 is twisted, when the mouth of the upper tube section 110 is unfolded, as long as any one of the two sides of the mouth of the upper tube section 110 contacts the corresponding travel switch 1 contact, the travel switch 1 is triggered to stop the tube belt machine. At this time, the tube tape 100 can be adjusted, the stable operation cycle of the tube belt machine is improved, and the occurrence of accidents related to the tube belt machine is reduced, which has certain economic benefits. In addition, this embodiment adopts a mechanical limit detection method, which does not require software or electronic component support, so it has the advantages of simple operation, stability and reliability, and fast response speed, avoiding the risk of electronic component failure or program error, and providing a more reliable and safe working environment for the staff.

[0035] like Figure 1 and Figure 3 As shown, optionally, the pipe conveyor also includes a window frame 3, and the pipe section roller frame group 2 includes a roller shaft 21 and a roller frame 22, the roller shaft 21 is rotatably connected to the roller frame 22, a plurality of roller shafts 21 are ring-arranged in the window frame 3, and a plurality of roller frames 22 are connected to the roller frame 22.

[0036] In this embodiment, Figure 1In the figure, six rollers 21 can be provided, and the six rollers 21 are arranged in a circle at equal angles in the window frame 3, and the six rollers 21 are connected end to end. In other words, the angle occupied by each roller 21 is 60°, and the tail transition section 130 and the head transition section 140 enter the space enclosed by the multiple rollers 21 to form the upper tube section 110 and the lower tube section 120.

[0037] like Figure 3 , Figure 5 and Figure 6 As shown, optionally, the pipe section roller frame group 2 also includes a pressure plate 23, a groove 221 is provided on the roller frame 22, the end of the roller shaft 21 is used to be rotatably connected in the groove 221, and a pressure groove 231 is provided on the pressure plate 23. When the pressure plate 23 is connected to the roller frame 22, the pressure groove 231 is used to abut against the end of the roller shaft 21 in the groove 221.

[0038] In this embodiment, after the pressure plate 23 is connected to the roller frame 22, the surface of the pressure groove 231 on the pressure plate 23 abuts against the end of the roller shaft 21 in the groove 221, thereby preventing the end of the roller shaft 21 from escaping from the groove 221, thereby improving the stability of the roller shaft 21 and further improving the stability of the conveying tube tape 100.

[0039] like Figure 3 and Figure 6 As shown, the pressure plate 23 is used for detachable connection with the roller frame 22. The roller frame 22 is also provided with first positioning holes 222 distributed on both sides of the groove 221. The pressure plate 23 is also provided with second positioning holes 232 distributed on both sides of the pressure groove 231. The first positioning holes 222 and the second positioning holes 232 are used for connection by bolts.

[0040] In this embodiment, the second positioning hole 232 on the pressing plate 23 and the first positioning hole 222 on the roller frame 22 can be connected by bolts, thereby facilitating the assembly and disassembly of the pressing plate 23 relative to the roller frame 22 .

[0041] like Figure 3 and Figure 6 As shown, optionally, the bottom of the groove 221 and the pressing groove 231 are both configured as arc surface structures.

[0042] In this embodiment, the curvature of the arc surface structure is adapted to the end of the roller shaft 21, so that when the pressure groove 231 abuts against the end of the roller shaft 21 in the groove 221, the arc surface structure at the bottom of the groove 221 and the arc surface structure of the pressure groove 231 form a circular hole, so that the end of the roller shaft 21 is rotatably connected to the circular hole, thereby improving the stability of the roller shaft 21 during rotation.

[0043] like Figure 3 and Figure 4As shown, optionally, the tube segment roller frame group 2 further includes a positioning plate 24 , and the roller frame 22 includes two symmetrically parallel mounting plates, the positioning plate 24 is connected between the two mounting plates, and the positioning plate 24 is used for detachably connecting with the window frame 3 .

[0044] In this embodiment, the two symmetrically parallel mounting plates have a certain spacing so that the roller shaft 21 can be installed between the two mounting plates. The two ends of the positioning plate 24 can be integrally formed with the two mounting plates, or can be connected to the two mounting plates by welding or screw connection. By making the positioning plate 24 detachably connected to the window frame 3, the entire pipe segment roller frame group 2 can be easily assembled and disassembled, thereby facilitating maintenance and replacement operations.

[0045] like Figure 4 and Figure 5 As shown, optionally, the pipe segment roller frame assembly 2 further includes a locking member 25 , and a third positioning hole 241 is provided on the positioning plate 24 . The locking member 25 is used to pass through the third positioning hole 241 and be connected to the window frame 3 .

[0046] In this embodiment, the locking member 25 can be a bolt. By setting a mounting hole at a corresponding position on the inner side of the window frame 3 , the third positioning hole 241 and the mounting hole can be connected by bolts, so that the positioning plate 24 is installed on the inner side of the window frame 3 .

[0047] like Figure 2 , Figure 8 and Fig. 9 As shown, optionally, the pipe conveyor further includes a bracket 5 , and the transition section roller frame group 4 has the same structure as the pipe section roller frame group 2 , and a plurality of transition section roller frame groups 4 are respectively connected to the bottom side and both sides of the bracket 5 .

[0048] In this embodiment, since the transition section roller frame group 4 has the same structure as the pipe section roller frame group 2, the structure diagram of each part of the transition section roller frame group 4 is not marked in the figure. The function of the transition section roller frame group 4 is to gradually transition the upper pipe section 110 from a round tube shape to a deep groove shape, a groove shape, and a plane. Therefore, the transition section roller frame group 4 is only arranged at the bottom and both sides of the bracket 5. Figure 8 and Fig. 9 In the figure, three rollers 21 can be arranged in the transition section roller frame group 4, one of which is installed at the bottom of the bracket 5, and the other two rollers 21 are installed on both sides of the bracket 5. Since the upper pipe section 110 gradually transitions from a round tube shape to a deep groove shape, a groove shape, and a plane, the inclination degrees of the rollers 21 in the transition section roller frame group 4 at different positions are different. Specifically, the closer the upper pipe section 110 is to the redirecting roller, the flatter it is, so that the closer the upper pipe section 110 is to the redirecting roller, the smaller the inclination degree of the rollers 21 in the transition section roller frame group 4 is to the redirecting roller, so that the upper pipe section 110 can gradually transition to a deep groove shape, a groove shape, and a plane.

[0049] like Figure 2As shown, optionally, two travel switches 1 are connected to both sides of the bottom of the bracket 5 .

[0050] Specifically, the travel switch 1 can be fixed on the bracket 5 by screw connection. Figure 2 In the process, the bracket 5 is installed on the head transition section 140 so that the bracket 5 is close to the last pipe segment roller frame group 2 in the conveying direction of the upper pipe segment 110. It should be noted that in actual use, according to the material flow conditions of the pipe conveyor, the operator can change the installation position of the travel switch 1 on the bracket 5, and make timely adjustments to the on-site limit contact distance to ensure signal stability.

[0051] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
